About   Contact    | 

High-alumina castable is an amorphous refractory material composed of bauxite clinker (aggregate), binder, and admixture. It can be used directly after adding water and stirring and is formed by vibration casting. High-aluminum castables need a certain amount of time for setting and hardening after construction, so they need to be cured for a certain period before they can be de-molded after casting.

How high alumina castable is produced?

High-alumina castables are based on traditional ingredients, reducing the amount of cement and adding different admixtures, thereby improving product performance, increasing temperature strength and load softening temperature, reducing thermal conductivity, and allowing high-alumina casting. The thermal stability of the material is better.
